  • Turning actuator plate 28 is interposed between the upper surface of the support 21 and the chuck jaws 26 and retained on the support 21 by the support pins 27 each received in one of slots 29 formed in the actuator plate 28 such that it can be turned a predetermined angle.
  • the actuator plate 28 has a central hole 30 in alignment with the passage 20 in the hollow support 21 and an integral arm 31 for turning the actuator plate 28.
  • the chuck jaws 26 can be turned around the support pins 27, each of the chuck jaws 26 is operatively connected to the actuator plate by engaging a rearward bend 33 of each chuck jaw 26 with one of notches 32 formed in the actuator plate 28.
  • the chuck jaws 26 may also be retained on the actuator plate 28 by fitting each of snap rings 34 in one of annular grooves 34 formed in the support pins 27.
  • a movable disk 36 has a circular opening 37 formed at the center thereof in alignment with the hole 30 in the actuator plate 28, and three apertures 38 formed in the movable disk around the central circular opening 37.
  • the movable disk 36 is mounted on the support pins 27 for vertical movement by loosely passing the support pins 27 in the apertures 38.
  • An annular rise 39 may be formed on the movable disk 36 around the central circular opening 37.
  • the movable disk 36 has an radially outwardly extending arm 40 which is located above an operating lever 43 of a microswitch 42 on a printed circuit board 41mounted in the housing 11.
  • a coil spring 44 is disposed around each of the support pins 27 between the movable disk 36 and each of the chuck jaws 26 to urge upwardly the movable disk 36, thereby preventing the arm 40 from depressing the switching lever 43 of the microswitch 42.
  • the arm 40 of the movable disk 36 depresses the switching lever 43 to switch close the microswitch 42.
  • the cover 13 has recesses 45 formed on the lower surface thereof around the central circular opening 13' and receiving the tops of the support pins 27 so that the cover 13 can be rested on the housing 11 at a predetermined position.
  • the annular rise 39 is received in the circular opening 13' in the cover 13 so that it can be exposed to the exterior.
  • a solenoid 46 is fixedly secured inside the housing and provided with a plunger 47 which performs liner movement upon energizing the solenoid 46.
  • the solenoid 46 also includes a reversed U-shaped bridge member 49 secured to the plunger 47 and having a pair of spaced-apart lugs 48.
  • the arm 31 of the actuator plate 28 is located between the lugs 48 and 48 of the bridge member 49 so that the liner movement of the bridge member 49 causes the actuator plate 28 to be turned via the arm 31.
  • a reduction geared electric motor 50 is secured to a raised bottom portion 51 of a bottom wall 19 of the housing 11 by means of set-screws 52 and has a output shaft 53 extending downwardly through the raised bottom portion 51 by which a space 54 is defined.
  • a spur gear 55 is fixed to the output shaft 53 within the space 54.
  • a ring gear 56 is formed in the inner wall of the receptacle 14 adjacent to the circular opening 15, and when the reduced diameter portion 16 of the housing 11 is fitted in the circular opening 15 of the receptacle 14, the spur gear 55 meshes with the ring gear 56.
  • a battery 57 used as a power source for the electric motor and solenoid.
  • Reference numeral 58 indicates a jack in which a plug of a electric cord from a charger is inserted to charge the battery 57.
  • the electric motor is intended not to be energized even if the microswitch 42 is operated.
  • Two luminous diodes 59, 60 on the printed circuit board 41 are located in two holes 61 in the cover 13, and one 59 of the luminous diodes indicates the operation of the apparatus while the other 60 indicates charging of the battery.
  • an injection needle 25 is attached to a syringe 23 by screwing a needle hub 25' onto threads on the barrel 24 at its forward end.
  • the injection needle 25 on the barrel 24 is inserted through the circular opening 13' in the cover 13 into the passage in the support 21.
  • a forward annular shoulder of the syringe 23 abuts the annular rise 39 around the central circular opening 37 in the movable disk 36.
  • the bridge member 49 is linearly moved by the solenoid plunger to push the arm 31 through the lugs 48, 48 in the same direction of the bridge member 49, thereby turning clockwise the actuator plate 28 a predetermined angle.
  • Turning of the actuator plate 28 causes its operatively associated chuck jaws 26 to be turned clockwise to their closed position around the support pins 27. Since the needle hub 25' of the injection needle 25 is in a position facing the chuck jaws when the syringe 23 is moved downwardly through the circular opening 13', the needle hub 25' is gripped from three ways by the closed chuck jaws 26.
  • the electric motor 50 is energized to rotate anti-clockwise the spur gear 55 fixed to the output shaft thereof so that the spur gear 55 revolves around the ring gear 56 on the receptacle 14.
  • the housing 11 is rotated relative to the receptacle to rotate the chuck device 22 on the support integral with the housing, relative to the syringe. Since the syringe 23 is held by hand, the rotation of the chuck device 22 permits the needle hub 25' of the injection needle 25 to be rotated anti-clockwise relative to the cartridge holder 24 of the syringe 23, thereby unscrewing the needle hub 25' from the cartridge holder.
  • the injection needle 25 remains gripped by the chuck jaws as long as the solenoid has been energized.
  • the circuit from the electric power source is opened via the control device to de-energize the solenoid 46 and electric motor 50.
  • the solenoid 46 is de-energized, the bridge member 49 is returned to its original position so that the actuator plate 28 is turned anti-clockwise to turn anti-clockwise the chuck jaws 26 to its opened position around the support pins 27.
  • the needle fitting 25' of the injection needle 25 is released from the chuck jaws 26 so that the injection needle 25 can fall through the passage 20 in the support 21 into the receptacle 14 for storage.
  • any rotative power transmission mechanism is not required to rotate the chuck device itself directly, thereby making the construction of the apparatus simpler and providing an apparatus of light weight.
